WaveWarp 2.0 Component
      
Dynamic Range Controllers:
Functional Description
Special-purpose component for
implementing a "limiter static curve" for use in the
element-by-element construction of a dynamic range limiter.
The control signal input is assumed to originate from the peak measurement
of an audio signal, converted to a logarithmic scale in base-2.
This "dB" signal measurement
is subtracted from the limiter threshold
(adjustable via the Parameter Window). If this difference is negative,
the control output is made equal to the difference, otherwise it is set
to zero.
It is intended that the output is sent to a Control AntiLog2
component for conversion from the logarithmic scale into a gain value.
IMPORTANT: This component is not intended for any use
other than the specialised application described above.
Algorithm
See
[Zo]
section 7.1 for an explanation of "static curves",
and section 7.3.1 for a discussion specific to the implementation
of a "limiter static curve". Note that, with respect to that reference,
the present limiter static curve is assumed to have a slope of 1.

It is assumed that the control input originates
from the peak measurement
of an audio signal, converted to a logarithmic scale in base-2, and that the
output is routed to an AntiLog2 component for conversion into a gain. |
